5; I To all whom it may concern;

Be it known that T, MAX Sonny, a citizen of the United States, residing in the city of New York, borough of'Brooklyn, county of-Kings, and State of New York, have invented a certain new and useful Improved Adjustable Grid, of which the following is a specification. r

This invention is an adjustablegrid for use with stoves and is particularly adapted to facilitate the :broiling of meats, fish, etc. The object of the invention is to provide an improved grid which may be readily adjustable as to height,.'. 6., distance fromthe heat, and at "the same time, provide means tofacilitate the mechanical movement of the grid into and outof the oven or housing in which grids are generall positioned.

The preferred form 0 adjustable gridof this invention embodies carrier members mounted for vertical travel at the opposite sides of'the oven and supporting the grid.

With these carrier members cooperate.

means for counter balancing the grid so that vertical adjustment {thereof maybe more readily accomplished by the employment of relatively little power exerted through an adjusting lever associated with at least one of the carrier members. Associated with the grid is a rock-shaft for imparting sliding movement to j the grid through operative connections, whichqrocke shaft is, in turn, actuated by a second operating lever. Through the operation of the first mentioned lever the grid may be ad;

' justed relative to the fire, whileithe operation of the second lever moves the grid in and out of the oven to facilitate'the positioning of the meats on or removing them from the grid, 1 The parts are thus counterbalanced and operate with great'ease irrespective of the welght on the grid.

Features of the invention, other ,than those specified, will be apparent from the following detailed description, when read in conjunction with the accompanying In the accompanyi v drawings, T have illustrated one practice embodiment of the present invention, but the construction therein shown is to be understood as illustrative, only, and not as defining the limits of the present invention.

Figure 1 'is an isometric view ofa embodying the present invention, the grld being here shown within an oven, as usual.

Application filed October 5, 1917. Serial No. 194,332.

fieferring to the drawings, A indicates a grid positioned within an oven B. The grid is'of the usual form and embodies a four sided frame a across the interior of which extend grid bars d. The grid is provided, at its'opposite side edges, with rollers 0 adapted to travel in tracks G, as shown best in Fig. 3. Keepers-0. are secured to the under side of the track C and extend upwardly and over the upper edge of-frame a to preclude the rollers from leaving the trackswhile allowing of the grid to be moved back and forth on said tracks.

The tracks'C are positioned at the opposite sides of the oven,"fl'interiorly thereof, and are supported from underneath by. suspension rods D which extend transversely through the oven and through vertical slots in the walls thereof. The opposite ends of said suspension rods D are tied together by bars E, as shown best in Fig. 1.

Secured on the-'gexterior sides of the oven area pair o t vertical". guides F between which-travel rollers'f, which are mounted. on the bars E. Extending across the back of the oven is a rock-shaft G, to the opposite ends of which is secured a pair of sustaining levers g g5 These .levers extend forwardly exteriorly, of the sides of the oven and are connectedvwith the bars E by links 9 The sustaining lever 9 extends forwardly only as far as the linlgg whereas the sustaining lever .g. is extended forwardly beyond the front edge of theoven to provide an operating handle 9 for oscillating levers g andy with thev rock-shaft G, as a fulcrum.

It will thus appear that the levers g and g are connected through links 9 and bars E with the supporting rods D by which the grid is carried, and it follows that if said ice levers are swung upwardly the grid will be raised while, if the levers are swung downwardly, the grid will be depressed. During this vertical travel of the grid, the supporting rods D travel in the slots d of the side walls of theoven. It is 61 the purpose of imparting this movement to the grid that lever g is made to project beyond the front of the oven so that, when the chef desires to raise or lower the grid, this re,'

'sult may be accomplished by operating the extension of said lever g. In order that minimum power may --be' employed in the manipulation. of the grid, as described, a plurality of weights H are connected with the upper ends of the links 9 by means of chains or cables 71, which run over direction rollers 72.. The weights H counter-balance the grid and minimize the force required for raising 0r lowering the same.

If the connection specified was all that was employed in the vertical manipulation of the grid, saidgrid would be apt to tilt if the weight was not perfectly distributed thereover and,'as this distribution of weight seldom'occurs, means is provided for obvlat- 2'6 ing the tilting under all circumstances. This means is in the form of two steadying rollers 2' which travel btween the guides F and are rigidly supported relative to the bars E by crossed strutsI secured at their point of crossing by rivets i, and also secured at theiropposite ends to'the bars E, as at '5 By this construction rocking of the bars E on the lower ends of the links 9 is entirely obviated, since it will appear that struts I,

rollers i and f, and bars E, collectively, formcarrier members for the supporting rods 1), one of which'carrier members is mounted on each side of the oven and is actuated, in its vertical travel, between. the guides F. All fear of rocking of the grid within the oven is thus entirely obviated and the grid may be raised or lowered at will by the manipulation of the'handle g thus'formed at the forward end of the extension of lever g. i

In order to obviate any chance of the grid becoming inadvertently depressed through the positioning of heavy broils, thereon, the handle 9 is provided with a stop y pivoted at y" and cooperating with the teeth of a rack J, mounted in any suitable manner at the front of the oven. The stop is preferably 'formed to gravitate into engagement -with the teeth of the rack and is adapted to be raised from said teeth when it is desired to lower the grid through the manipulation of an operating finger 7' associated therewith. By the construction specified the grid may be raised or lowered at will and locked in any predetermined position.

In the accompanyingdrawings and in the interest of clearness,'only the lower portion of the oven is shown, the extreme upper portion thereof .being cutaway. It will be understood that said extreme upper portion of the oven is formed as usual and. houses the burners or embers. As both of these means of producing heat for broiling the meats on the grid are-old and well known in the art, it is not thought necessary to show them in the drawings, as they would obscure the invention without adding anything to the disclosure.

Aside from the. vertical adjustment of the grid, as hereinbefore described, means is provided for mechanically moving the grid back and forth on the tracks C. This means embodies a rock-shaft K extending across a portion of the back of the oven, and exteriorly thereof. To the rock-shaft K is fixed an arm is, to the free end of which is pivoted a link is pivotally secured to a luglc formed on the grid A, as shown in Fig. l. Tothe opposite end of rock-shaft K is fixed 'a segmental rack L which meshes with a position wherein its free end may be grasped for the purpose .of operating the lever. When the lever Z is depressed, it operates through'the segmental racks Z and L to osci-llate the rock-shaft K and throw thearm k vr'earwardly. This movement of the arm is draws the link is after it and moves the grid from the position of Fig. 1, wherein it projects beyond the front of. the oven, to a position wherein it is entirely within the oven. When the lever Z" is elevated the grid is again moved, through the connections described, to the position shown in Fig. 1. In this manner the grid may be rolled back and forth on the tracks C from the exterior position shown, and wherein the broils may be readily positioned upon said grid, to a position within the oven to place the broils directly beneath the fire.

It thus appears that the present. invention allows of two distinct adjustments; firstly, the forward ad ustment of the grid relative to the fire, and, secondly, the sliding adjust-. i

without departing from the spirit of the in vention, which is to be understood as broadly novel as is commensurate with the appended claims.

Having thus fullydescribed the invention Letters Patent, is
